In engineering, the mass transfer coefficient is a diffusion rate constant that relates the mass transfer rate, mass transfer area, and concentration change as driving force: kc=nA/AΔcA Where: kc is the mass transfer coefficient [mol/(s·m²)/(mol/m³)], or m/s nA is the mass transfer rate [mol/s] A is the effective mass transfer area [m²] ΔcA is the driving force concentration difference [mol/m³]. This can be used to quantify the mass transfer between phases, immiscible and partially miscible fluid mixtures (or between a fluid and a porous solid).
